| 中文摘要:川西北高原高寒山区若尔盖铀矿地层“漏失、垮塌、超径、孔斜”，是典型的“五毒俱全”、国内少见的钻探复杂地层。我们通过认真的分析和研究，从工艺技术上改进，采用优质泥浆体系，成功穿越了近300米的炭质板岩层；采用连续造斜器成功实施了深孔定向钻进，为在复杂地层下一基多孔工艺提供了依据。 |

| Abstract:Uranium deposits in ruoergai, Northwest Sichuan plateau high stratum "leak, collapse, oversized, hole deviation ", is typical of the "deadly venoms and taste", rare domestic drilling complex formations. Through careful analysis and research, the technology improvement, of high quality mud system, successfully crossed the nearly 500 metres of carbonaceous rocks; continuous whipstocking successfully implement deep-hole directional drilling, provided a basis for hole in Quito, under complex formation. |
